Well, I made madman.wad, then I thought there should be some new sounds, so that`s the only difference between this one and the old madman.wad. It changes all the music of doom2 to better stuff like alice in chains, silverchair, korn, metallica, tool, and lots of others. New rocket Launcher, shotgun, Pistol, chaingun, plasma rifle and BFG sounds. There are a few other sounds as well, but I forget what all of them are...
